My personal configs for a Prusa i3 / RAMPS

This is a Prusa i3 with a 200^2mm bed, Arduino Mega2560 RAMPS, and a
G3D LCD Panel. This build leaves ~3K of SRAM, which is used in part to
optimize and sort file listings on the SD card. I added defines in
Configuration.h taking advantage of the compiler’s ability to calculate
values (and name them) instead of inserting pre-calculated values.
